Engine SFX updates

Base AC Aventador SV vs ECU Tuner Aventador

What's new:

🔥 Resonance System

Dynamic attack/decay triggered by engine power changes

"Echo without echo" tail modulation for pulsating rumble

Special engine braking effects with extended singing tails

⚡ Backpressure Shimmer

Engine power-linked shimmer intensity

Dynamic flange modulation for realistic exhaust breathing

RPM & valve lift responsive character

🎯 Firing Pulse Simulation

V10/V12/V6 specific bank phasing

Micro jitter for organic engine feel

Authentic dual-bank V-engine simulation

🛠 Cam Lift & Duration

Realistic RPM-based valve lift profiles

Dynamic overlap calculation from lift × duration Instant response to rapid lift changes

Throttle-modulated lift behavior

Result: Engines now breathe with resonance, shimmer with backpressure, pulse with authentic firing order, and respond dynamically to valve timing.
